I've looked through bluez sources for 2.6.12 and found the "reset" 
parameter in the hci_uart driver. However, I need to use the MontaVista 
kernel on this phone. Nevertheless I have modified hci_uart driver to 
set the appropriate quirks flag, and verified with hcidump that it sent 
a reset on "hciconfig up". However this still does not work.

The phone's native stack though, still works fine. Unlike bluez, it does 
not read the the BD_ADDR from the chip, which makes sense because it 
programs the address into the chip...
